Conventional Gate Valves StreamFlo

Parallel Expanding Gate Valve This unidirectional expanding gate valve gives an extraordinarily high mechanical seating seal force that acts simultaneously against both seats. The seating force is not affected by line pressure fluctuations or vibrations.

Gate Valves Information Engineering360

Some parallel gate valves are designed to allow the seat to be springenergized by an elastomer that applies constant pressure to the disk gate seating surface. In the doubledisk parallelseat type, the valve is closed by lowering the disks from the valve neck to a height equal to that of the valve seats.

What is a gate valve? Where is it used, and for what?

The parallel gate valves use a flat gate between two parallel seats, and a popular type is the knife gate valve designed with a sharp edge on the bottom of the gate. The wedgeshaped gate valves use two inclined seats and a slightly mismatched inclined gate.

Gate Valves I Isolation Valves Alberta, BC and

All gate valves are not created equal, and there are several different technologies to consider when choosing a gate valve for a specific application including wedge gate, slab gate, conduit gate, expanding compact gate, parallel slide gate, and single disc.

Parallel Gate Valve China Valve Manufacturer Metals Valve

The parallel gate valves are slide valves with a parallelfaced gatelike closure member including knife gate valve series and through conduit gate valve series. The closure member can be ether single disc or double discs, soft seated or metal seated.

Parallel slide gate valves Babcock Valves

Parallel slide gate valve with equalizer Babcock valves also design and manufactures parallel slide gate valves, that avoid any flow turbulence, and minimize the pressure drop. The parallel slide gate valves are an alternative option of double disc valves, having single wedge instead of double wedge. The horizontal spring keeps the discs in

GUIDANCE ON VALVE TYPE SELECTION b.ricardo

Parallel Expanding Gate valve. This valve has a split gate with parallel sealing faces, inclined internal surfaces, and parallel seats. The two gate halves are forced out against the seats at point of closure, providing a tight seal without the assistance of fluid pressure. Seats may be fixed or floating.

PARALLEL GATE VALVES Engineering360

Parallel gate valves are slide valves with a parallelfaced gatelike closure member. This closure member may consist of a single disc or twin discs with a spreading mechanism in between. Typical valves of this type are shown in Figure 325 through Figure 332. Figure 325 Parallel Slide Gate Valve

FLUITEK ORSENIGO VALVES has very extended experience in manufacturing this type of valve. They are an alternative to the traditional flex wedge type gate valves. The disc is in two halves, spring loaded, that seat on parallel seat rings.

Gate Valves SAMSON

Parallel Gate Valves Parallel Slide Gate Valves For those applications when large temperature variations are expected or fast shutoff is required, this is the most ideal design. The seats are parallel and the disc has no contact with the seats during the stroke of the valve.

Gate Valves Information Engineering360

The parallel gate valve uses a flat disc gate between two parallel seats, upstream and downstream. Shutoff is obtained by the freefloating seat or disk gate allow the upstream pressure to seal the seat and disk against any unwanted seat leakage.

Gate Valve Types, Construction, Applications and Advantages

Like the doubledisc or parallelseated gate valve, its disc seats against the downstream seat, depending on the flow direction. The inside diameter of a conduit gate valve is equal to the inside diameter of the connecting pipe.
